Abstract
Neurotrophins and neuropeptides are the essential regulators of peripheral nociceptive nerves that help to induce, sensitize, and maintain pain. Neuropeptide has a neuroprotective impact as it increases trophic support, regulates calcium homeostasis, and reduces excitotoxicity and neuroinflammation. In contrast, neurotrophins target neurons afflicted by ischemia, epilepsy, depression, and eating disorders, among other neuropsychiatric conditions. Neurotrophins are reported to inhibit neuronal death. Strategies maintained for "brain-derived neurotrophic factor (BDNF) therapies" are to upregulate BDNF levels using the delivery of protein and genes or compounds that target BDNF production and boosting BDNF signals by expanding with BDNF mimetics. This review discusses the mechanisms of neurotrophins and neuropeptides against acute neural damage as well as highlighting neuropeptides as a potential therapeutic agent against Parkinson's disease (PD), Huntington's disease (HD), Alzheimer's disease (AD), and Machado-Joseph disease (MJD), the signaling pathways affected by neurotrophins and their receptors in both standard and diseased CNS systems, and future perspectives that can lead to the potent application of neurotrophins and neuropeptides in neurodegenerative diseases (NDs).

Abstract
Introduction: Parkinson disease (PD) is the second most common neurodegenerative disease affecting older individuals with signs of motor disability and cognitive impairment. Epicatechin (EC) and edaravone have neuroprotective effects most probably due to their antioxidant activity; however, a limited number of studies have considered their role in PD. This research aimed at investigating the neuroprotective effect of EC and edaravone in a neurotoxin-induced model of PD. Methods: An in vitro model of PD was made by subjecting SH-SY5Y neuroblastoma cells to neurotoxin: 6-hydroxydopamine (6-OHDA) 100 μM/well. The cytoprotective effect of EC and edaravone in five concentrations on cell viability was tested using the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay. The apoptotic assay was done by annexin V and propidium iodide method using flow cytometry. Results: According to the MTT assay analysis, EC and edaravone had protective effects against 6-OH DA-induced cytotoxicity in SH-SY5Y neuroblastoma cells that were much more significant for edaravone and also a relative synergistic effect between EC and edaravone was observed. The apoptotic analysis showed that edaravone alone could decrease early and late apoptosis, whereas EC diminished early apoptosis, but enhanced late apoptosis and necrosis. Besides, co-treatment of edaravone and EC had a synergistic effect on decreasing apoptosis and increasing cell viability. Conclusion: The protective effect of edaravone on apoptosis and cytotoxicity was demonstrated clearly and EC had a synergistic effect with edaravone.

Abstract
Anxiety in Parkinson's disease (aPD) is underdiagnosed, undertreated, and understudied. As many as 50% of persons diagnosed with Parkinson's disease (PD) are reported to suffer from anxiety. Current treatment is largely pharmacologic, which can result in a myriad of undesirable and unsafe side effects. The aim of this paper is to examine intervention studies of self-managed nonpharmacological strategies for the treatment of anxiety. A comprehensive review was conducted on experimental or quasi-experimental trials that included self-management approaches for the nonpharmacologic treatment of anxiety as a primary or secondary aim or outcome measure. Thirteen studies were identified from four databases. Study quality demonstrated variability in design and delivery of self-managed interventions; sample sizes were small; anxiety was most commonly a secondary aim; and the use of anxiety measures varied widely. Statistical significance was evident in slightly more than 50% of the anxiety intervention studies. A common element in the interventions in all studies was the focused use of breath. Further research is needed to determine the feasibility of using focused breathing, alone, as an intervention for the self-management of anxiety in Parkinson's disease.

Abstract
The purpose of this study was to compare acute cardiometabolic responses to 3 modes of treadmill exercise in adults diagnosed with Parkinson's disease (PD). Eight elderly adults with PD (67.9 ± 3.0 yr) completed 1 session each on a land, aquatic, and antigravity treadmill at 50% body weight. Participants walked from 1 to 3 mph in 0.5-mph increments at 0% grade for 5 min at each speed. Heart rate, energy expenditure, blood pressure, and rating of perceived exertion were measured at rest and during exercise. All variables except diastolic blood pressure increased with speed on all treadmills (p < .001). At all speeds except 1.5 mph, heart rate was higher on the land treadmill than the antigravity treadmill (p < .05). Exercising on an aquatic or antigravity treadmill elicits similar submaximal physiologic responses to exercise on a land treadmill in adults with PD.

Abstract
BACKGROUND Parkinson's disease (PD) is a degenerative disorder that leads to a decrease in cognitive performance and affects patients' quality of life (QoL). The purpose of this study was to investigate the QoL of PD patients and their caregivers in relation to each patient's cognitive impairment. METHODS A total of 60 subjects with idiopathic PD were recruited; all had a primary caregiver. Patients' cognitive abilities were evaluated by the Mini-Mental State Examination, the Activities of Daily Living Scale, and the Instrumental Activities of Daily Living Scale. The 39-item Parkinson's Disease Questionnaire and the 36-item Short Form Health Survey were used to assess the QoL of patients and caregivers, respectively. RESULTS The Mini-Mental State Examination was a significant predictor of most of the QoL subscales, including mobility, stigma, social support, cognition, and physical discomfort. The Activities of Daily Living Scale and the Instrumental Activities of Daily Living Scale were significant predictors of mobility, activities of daily living, and cognition. Patients' clinical conditions also significantly affected all of the 36-item Short Form Health Survey subscales; predicted physical functioning, bodily pain, vitality, and social role functioning on the Activities of Daily Living Scale; and predicted physical functioning, physical role functioning, and emotional role functioning on the Mini-Mental State Examination. CONCLUSIONS Our results confirm a relationship between PD patients QoL and the perceived burden of their caregivers. Indeed, patients' cognitive impairment strictly correlated to lower QoL scores in both patients and caregivers and is a strong predictor of caregiver stress and burden. These results emphasize the importance of implementing early interventions to prevent or ameliorate caregivers' burnout.

Abstract
Pain is a distressing non-motor symptom experienced by up to 85% of people with Parkinson’s disease (PD), yet it is often untreated. This pain is likely to be influenced by many factors, including the disease process, PD impairments as well as co-existing musculoskeletal and/or neuropathic pain conditions. Expert opinion recommends that exercise is included as one component of pain management programs; however, the effect of exercise on pain in this population is unclear. This review presents evidence describing the potential influence of exercise on the pain-related pathophysiological processes present in PD. Emerging evidence from both animal and human studies suggests that exercise might contribute to neuroplasticity and neuro-restoration by increasing brain neurotrophic factors, synaptic strength and angiogenesis, as well as stimulating neurogenesis and improving metabolism and the immune response. These changes may be beneficial in improving the central processing of pain. There is also evidence that exercise can activate both the dopaminergic and non-dopaminergic pain inhibitory pathways, suggesting that exercise may help to modulate the experience of pain in PD. Whilst clinical data on the effects of exercise for pain relief in people with PD are scarce, and are urgently needed, preliminary guidelines are presented for exercise prescription for the management of central neuropathic, peripheral neuropathic and musculoskeletal pain in PD.

Abstract
AIM The purpose of the study was to identify the role of the Parkinson's disease specialist nurse in providing support both for people with Parkinson's disease (PD) and their spouses. BACKGROUND PD is a neurodegenerative disease with symptoms that affect many aspects of daily life. In Sweden, specialised nurses called Parkinson's disease specialist nurses (PD specialist nurses) have been working for over a decade to support PD patients and their families. METHOD A qualitative approach was taken using dyad interviews with each PD patient and spouse. The analysis was conducted using conventional qualitative content analysis. FINDINGS The analysis resulted in the identification of one overarching category; competent, professional practice, tailored for the individual. Four categories: professional competence, nursing practice, continuity of contact and emotional support, are distinct but related to each other and show different nuances of the same phenomenon. CONCLUSION The work of PD specialist nurses in providing support to PD patients and their relatives should be tailored to individual patients and their families as well as including skilled nursing care to relieve the impact of the disease on daily life.

Abstract
Background Parkinson’s disease (PD) is the second most common neurodegenerative disorder affecting the senile population with manifestation of motor disability and cognitive impairment. Reactive oxygen species (ROS) is implicated in the progression of oxidative stress-related apoptosis and cell death of the midbrain dopaminergic neurons. Its interplay with mitochondrial functionality constitutes an important aspect of neuronal survival in the perspective of PD. Edible bird’s nest (EBN) is an animal-derived natural food product made of saliva secreted by swiftlets from the Aerodamus genus. It contains bioactive compounds which might confer neuroprotective effects to the neurons. Hence this study aims to investigate the neuroprotective effect of EBN extracts in the neurotoxin-induced in vitro PD model. Methods EBN was first prepared into pancreatin-digested crude extract and water extract. In vitro PD model was generated by exposing SH-SY5Y cells to neurotoxin 6-hydroxydopamine (6-OHDA). Cytotoxicity of the extracts on SH-SY5Y cells was tested using MTT assay. Then, microscopic morphological and nuclear examination, cell viability test and ROS assay were performed to assess the protective effect of EBN extracts against 6-OHDA-induced cellular injury. Apoptotic event was later analysed with Annexin V-propidium iodide flow cytometry. To understand whether the mechanism underlying the neuroprotective effect of EBN was mediated via mitochondrial or caspase-dependent pathway, mitochondrial membrane potential (MMP) measurement and caspase-3 quantification were carried out. Results Cytotoxicity results showed that crude EBN extract did not cause SH-SY5Y cell death at concentrations up to 75 μg/ml while the maximum non-toxic dose (MNTD) of water extract was double of that of crude extract. Morphological observation and nuclear staining suggested that EBN treatment reduced the level of 6-OHDA-induced apoptotic changes in SH-SY5Y cells. MTT study further confirmed that cell viability was better improved with crude EBN extract. However, water extract exhibited higher efficacy in ameliorating ROS build up, early apoptotic membrane phosphatidylserine externalization as well as inhibition of caspase-3 cleavage. None of the EBN treatment had any effect on MMP. Conclusions Current findings suggest that EBN extracts might confer neuroprotective effect against 6-OHDA-induced degeneration of dopaminergic neurons, particularly through inhibition of apoptosis. Thus EBN may be a viable nutraceutical option to protect against oxidative stress-related neurodegenerative disorders such as PD.

Abstract
AIMS To determine the impact of a Parkinson's medicine education program on nurses' knowledge and practices in two settings where people with Parkinson's disease are cared for: hospitals and residential aged care facilities. The Parkinson's Disease Medication Protocol Program aimed to increase nurse knowledge of Parkinson's medication administration and safety in care management in order to improve health outcomes, function and well-being for the person with Parkinson's. BACKGROUND The ageing demographic of the developed world is concomitant with an increase in chronic disease, with Parkinson's disease being one of the most debilitating and costly. Individually complex medication regimens and unique spectrums of symptoms require disease-specific knowledge in nurses. People with Parkinson's disease admitted to hospitals and/or living in residential aged care facilities often have multiple co-morbidities, rendering care more complex still. Nurse ignorance of Parkinson's disease medicines, their uses, side effects and administration regimens, and safe care practices, can cause unnecessary distress and dysfunction for the person. METHOD The two pilot studies employed an eighteen month pre/post-test/follow up design at different time frames, using a questionnaire developed by the study team and an expert panel to evaluate nurses' self-assessed 'perceived' knowledge and actual knowledge of Parkinson's disease, Parkinson's medicines and safe care practices, and satisfaction with the targeted Parkinson's education program. RESULTS/FINDINGS Nurses in the hospital pilot (2006/8) revealed deficits in pre-test perceived and actual knowledge levels, which increased significantly at post-test and follow-up. In contrast, in the residential aged care pilot (2008/10) the nurses had higher perceived and actual (correct) knowledge relevant to experience at pre-test and these levels increased at follow-up. Both pilot study cohorts were very satisfied with the PDMPP as an education and support vehicle in Parkinson's management. CONCLUSION These study results concur with the international literature which identifies that without targeted clinical education nurses do not necessarily have sufficient knowledge to effectively manage Parkinson's medicines and avoid unnecessary negative outcomes arising from delays, errors and omissions, nor do they know how to provide safe and effective care for persons with Parkinson's. A well-developed and resourced Parkinson's medicine education program, such as the PDMPP, has the potential to improve deficits in clinical practice.

Abstract
Background To identify key non-motor symptoms of Parkinson's disease (PD) to include in a daily diary assessment for off-time, revise the Scales for Outcomes of Parkinson's disease Diary Card (SCOPA-DC) to include these non-motor symptoms, and investigate the validity, reliability and predictive utility of the Revised SCOPA-DC in a U.S. population. Methods A convenience sample was used to recruit four focus groups of PD patients. Based on findings from focus groups, the SCOPA-DC was revised and administered to a sample of 101 PD patients. Confirmatory factor analysis was conducted to test the domain structure of the Revised SCOPA-DC. The reliability, convergent and discriminant validity, and ability to predict off-time of the Revised SCOPA-DC were then assessed. Results Based on input from PD patients, the Revised SCOPA-DC included several format changes and the addition of non-motor symptoms. The Revised SCOPA-DC was best represented by a three-factor structure: Mobility, Physical Functioning and Psychological Functioning. Correlations between the Revised SCOPA-DC and other Health-Related Quality of Life scores were supportive of convergent validity. Known-groups validity analyses indicated that scores on the Revised SCOPA-DC were lower among patients who reported experiencing off-time when compared to those without off-time. The three subscales had satisfactory predictive utility, correctly predicting off-time slightly over two-thirds of the time. Conclusions These findings provide evidence of content validity of the Revised SCOPA-DC and suggest that a three-factor structure is an appropriate model that provides reliable and valid scores to assess symptom severity among PD patients with symptom fluctuations in the U.S.

Abstract
PURPOSE The study was done to identify lower urinary tract symptoms (LUTS) and to evaluate the factors affecting LUTS for the people with Parkinson's disease. METHODS The research design was a cross-sectional study with interviews using a structured questionnaire. The participants were 72 patients with Parkinson's disease who were seen in the Neurology clinic of a university hospital from September to November 2005. RESULTS Mean score of LUTS for the participants was 10.11. In each symptom score of LUTS (range 0-5), weak stream was the highest 2.06, followed by nocturia 1.71, and urgency 1.61. The severity of LUTS was moderate to severe group for 51%. LUTS were significantly different by regular exercise. Positive correlations were observed between Hoehn and Yahr stage (stage of disease severity) and frequency and between Hoehn and Yahr stage and urgency (r=.280, p=.018; r=.328, p=.005). LUTS were significantly predicted by regular exercise (p=.001) which explained 15.0% of the variance in LUTS. CONCLUSION Regular exercise was found to be a very important factor associated with LUTS for patients with Parkinson's disease.

Abstract
BACKGROUND Parkinson disease (PD), a chronic neurodegenerative disease, has been proposed to be a multifactorial disorder resulting from a combination of environmental mechanisms (chemical, infectious, and traumatic), aging, and genetic deficits. Microglial activation is important in the pathogenesis of PD. OBJECTIVES We investigated dopaminergic (DA) neurotoxicity and the underlying mechanisms of formyl-methionyl-leucyl-phenylalanine (fMLP), a bacteria-derived peptide, in relation to PD. METHODS We measured DA neurotoxicity using a DA uptake assay and immunocytochemical staining (ICC) in primary mesencephalic cultures from rodents. Microglial activation was observed via ICC, flow cytometry, and superoxide measurement. RESULTS fMLP can cause selective DA neuronal loss at concentrations as low as 10(-13) M. Further, fMLP (10(-13) M) led to a significant reduction in DA uptake capacity in neuron/glia (N/G) cultures, but not in microglia-depleted cultures, indicating an indispensable role of microglia in fMLP-induced neurotoxicity. Using ICC of a specific microglial marker, OX42, we observed morphologic changes in activated microglia after fMLP treatment. Microglial activation after fMLP treatment was confirmed by flow cytometry analysis of major histocompatibility antigen class II expression on a microglia HAPI cell line. Mechanistic studies revealed that fMLP (10(-13) M)-induced increase in the production of extracellular superoxide from microglia is critical in mediating fMLP-elicited neurotoxicity. Pharmacologic inhibition of NADPH oxidase (PHOX) with diphenylene-iodonium or apocynin abolished the DA neurotoxicity of fMLP. N/G cultures from PHOX-deficient (gp91PHOX-/ -) mice were also insensitive to fMLP-induced DA neurotoxicity. CONCLUSION fMLP (10(-13) M) induces DA neurotoxicity through activation of microglial PHOX and subsequent production of superoxide, suggesting a role of fMLP in the central nervous system inflammatory process.
